Can thermomedic therapy garments help relieve the pain of tendonitis?

NEver heard of it. I had to looks this up, its not something I have ever heard of , i don t have any opinion but would wan to see some valid randomized peer reveiwd studies or a lot of results over time rather than just some claims that it works.
Warm and fuzzy??? Heat as a therapeutic tool has been benificial for soft tissue injuries; as to whether the 'brand' of garment you are discussing will do the trick depends upon the reputation of the manufacturer. As i tell all of my patients; "let the buyer beware"!
